This study examined the effects of drying temperatures (25 and 45 °C) on the physical properties
of different formulations of gelatin/CMC/chitosan composite films. The physical properties
of each formulated film were assessed via Fourier Transform Infra-Red (FTIR) spectroscopy,
X-Ray Diffractometry (XRD), Water Vapour Permeability (WVP) and biodegradability. The
incorporation of CMC and chitosan significantly influenced film properties. Increased chitosan
concentrations reduced the film’s amorphous character by increasing its crystalline structure.
The blended films also exhibited amino peaks that shifted from 1542 to ~1548 cm-1 while NH
and/or OH peaks shifted from 3384 to 3288 cm-1. Formulation E had the second lowest WVP
for both drying condition and the highest weight loss for biodegradability after burial in soil for
5 days. In conclusion, different temperature did not affect the properties of film produced and
formulation E qualified as ‘high quality packaging material’ with promising potential for the
food packaging industry.
